Should a candidate want an easy mobile job application method (given the technology of today) they need to load a standard resume into the cloud (a job adversing website). When an add of interest takes them they apply for that job and the job ad web site attaches their resume to an application for them - QED.

Have a look at the Jobezy.com.au web site as an example of such a site that does not use an app rather relies for its communication on email to the candidates, broadcasting relevant job ads, and to the employer for applications& resumes.

The downside to this method and inherent in the current technology is that everyone has to put up with a standardised resume - in fact most candidates rely on a standard in any event.
